I got this set several months ago and am overall quite satisfied. I do have an issue with the 3D that I have not seen mentioned yet here and also have yet to find anything in my internet searches covering it (though not knowing what the issue is called, the correct search terms are anyone's guess).
the issue is as follows:
when watching 3D content, the display appears as if it is constantly adjusting much like the way a cameraman that can't decide what to focus on. the "double-image" will come together and spread apart at seemingly random intervals and durations.
this is not an issue with eye-strain, nor does it have anything to do with the glasses that I can tell-- you can see the set doing it without wearing the glasses where on the left and right edges of the screen, you can see vertical black bars going narrow and wide.
I haven't been able to tell if it is dependent on the amount of "action" showing on screen, or if it is completely random.
This issue occurs with seemingly any type of 3D I try to watch:
3D bluray discs (PS3 through HDMI to Onkyo [TX-NR616] receiver to TV), 2D to 3D conversion any source), side-by-side 3D (mostly from images and video played from PC via HDMI cables), content from the built-in "3D World"
I'm pretty sure the HDMI cables are the newest version and quite capable of 3D content.
has anybody else had this issue? this surly isn't normal.
